SANFORD A. MOSS, OF LYNN, MASSACHUSETTS, ASSIG-NOR TO GENERAL ELECTRIC COMPANY, A CORPORATION 0F NEW YORK.

REGENERATOR.

Specification of Letters Patent. Patented Allg'. 15, 1911.

Original application led December 31, 1904, Serial No. 239,089. `Divided and this application led April 4,

1906. Serial No. 309,836.

To all whom it may concern.'

Be it known that I, SANFORD A. Moss, a citizen of the United States, residing` at Lynn, in the county of Essex, State of Massachusetts, have invented certain new and useful Improvements in Regenerators, of which the following is a specification.

The present invention is a division of my application Serial No. 239,089, iled Dec. 31, 1904, which division is made at the requirement of the United States Patent Olice under the'provisions of. Rules 41 and 42.

y Thel invention relates to regenerators wherein the heatcontained in one body of fluid isLtransterred to another, the fluids being provided with separate conduits or passages to prevent mixing.

The object of the invention .is to provide a regenerator ot the characterl 'speciod which will etliciently transfer the heat from one body of fluid to another. and is simple and rugged in construction.

In the accompanyingdrawings illustrating one of the embodiments `of the invention, Figure 1 is a sidel elevation'of a combustion chamber, gas turbine and regenerator; Fig. 2 is a Vvertical section of-xthe regenerator; Fig. 3 is a view of the` regenerator with the cover removed; and Fig.y 4 is a sectional view taken on a line just below the head which supports the air carrying tubes.

1 represents a chamber in which combus- .tion under pressure takes place continuouslywhile the apparat-us is in operation. The products of combustion from the chamber pass through nozzles or other discharging devices 2 into theturbine 3 and rotate the bucket wheel. The exhaust gases escape by a conduit into tlieregenerator and there heat the incoming air before it enters the vcombustion chamber.

Referring to Figs. 2 to 4, inclusive, the construction of the regen'erator will be described. 4 represents a support which is mounted upon suitable standards 5' so that the exhaust-receiving conduit G will be in a position to receive the exhaust gases directly from the turbine, and this without undue loss of heat fromradiation` Mounted Within the casing of the regenerator is a castmetal base 7 that is provided with a chamber 8 to receive the air after it has been passed through the coils of pipe 9. Rising vertically above the base is a tubular column 10 y umn. In the present illustration a numberA of metal loops 16 are provided which extend between the concentric turns. of the coils and` at their lower ends form a support for a sec- -tion of the coll by engaging one of its turns. As shown in Fig. 4, the coils 9 are connected to the head'11 by connectors 17. The coilsv .Y may be connected in any suitable manner.

In the present instance they are connected in multiple between the base 8 and the head 11, although other arrangements can .be provided if desired. The connection `between the lower ends of the coils andl the4 base is by means of connectors 18. Located between Athe coils and the metal'casing 19 is a lining 20 of heat-resisting material. The outside of the casing is preferably covered by a lagging 21 of suitable .materialv to'retain the heatwithin the inclosure. The upper end of the casing is provided with a conduit 22 for/ 85:

discharging the exhaust lgases after they have given up a considerable amount of"l their 'heat to the compressed air contained in the coils 9. Situated-directly below the-conduit 22 is an opening 23 in the upper head which conveys exhaust products from the. interior of the casing to the exhaust' conduit. In addition to this opening 'the products' can pass through the spaces-24 as shown in Figs.

and 4. It is tobe noted -that the air enters the regenerator at its coolest point and flows toward the point of greatest temperature,

namely toward the exhaust-receiving c011- duit 6. The exhaust conduit 6 is srounded` wardly opening safety valves responding to increases inpre'ssure in the regenerator. In the construction shown an outwardly opening passage 28 is provided which is'nor- Inallyclosed'by the hinged plate '29, the latter being weighted to a greater or less extent i so that 1t will close by gravity. The inner face of this late or valve is protected by a suitable facing of heat-resisting material.

Situated in front of the opening and carried by posts or other supports from the casing,

l is a plate SOIwhich restricts the zone of the lames'issuing from the passage 28. As many of these arrangements may be provided as are necessary to properly protect the apparatus, and they may be located as shown or at different points.

In accordance with the provisions of the patent statutes, I have described the principle of operation of. my invention, together with the apparatus which I now consider to represent the bcst embodiment thereof; but I desire to have it understood that the apparatus shown is onlyillustrative, and that the invention can be carried out by other means.

W'hat I claim as new and desire to secure by Letters Patent of the United States, is,-

l. In a regenerator for gas turbines, the combination of a chambered receptacle, a conduit for conveying the exhaust gases from the turbine into the receptacle, a second conduit arranged to form an elongated passage for the gas to be heated, and a chamber'urrounding the exl'iaust-conveying conduit through which the gas passes prior Ato being discharged.

2. In a regenerator, the combination of a chambered base, a support mounted thereon, a coil of pipe carried by the support and 'discharging into the chambered base, a casing inclosing the coil of pipe, and a doublewalled conduit having passages for conveying hot gases to the interior'of the casing to heat the coil of pipe and also for conveying the contents of the coil outwardly.

3. Ina regenerator, the combination of a gas to be heated Within the casing, means for supplying exhaust from an engine to the interior of t-he Acasing to flow over the outside of said conduit'and increase the temperature of its contents, a safety device' which discharges outwardly fromthe casing when the pressure therein becomes excessive, and means mounted on the casing lfor deflecting said discharge.

4. In a regenerator, the combination of a casing, a conduit within the casing through which a medium to be heated circulates, a conduit for conveying exhaust gases from a prime mover into the interior of the casing, a chamber surrounding the exhaust conveyving conduit' through which said medium passes as -it leaves the regenerator, and a safety device which relieves 'the pressure within the casing when it exceeds a predetermined amount.

' 5. In aregenerator, the combination of a caslng, a .chambered base therefor, a cenv trally located column supported by the base,

a chambered head mounted on the column, a coil ofpipe for conveying Huid, arms projecting from the column by which `the coil is supported intermediate the head and base, means connecting the ends of the coil to the chambers in the head and base, aconduit for conveying hot gases to the interior of the casing, and a conduit for discharging the gasesafter they have given up heat to the fluid passing through said coil.

6. In a regnerator, the combination of a f cylindrical casing, a chambered base therefor, a column projecting upwardly from the center of the base, a chambered head mounted on the top of the'column, radial armsv on the column adjacent the lower side.

and a conduit supplying gas or air to one of said chambered membersto be heated in the coils by saidexhaust gases.

7. In a regenerator,.the combination of a casing, a chambered base therefor, a chambered head,'pipes having their ends connected tothe chambers in the base andhead, a conduit connected to the interior of the casing for conveying 'luid to said interior, a conduit surrounding the rst conduit and connected to the chamber in the base, a conduit connected to the chamber in the head, and a conduit leading from the interior' of the casing.
